TRUCK.

Application filed October 4., 1913.

To all whom it may concern:

Be it known that I, WILLIAM OSCAR SHAD- BOLT, a citizen of the UnitedStates, and a resident of the city and State of New York, have inventedcertain new and useful Improvements in Trucks, of which the following isa specification.

This invention relates to motor trucks in which the chassis and the loadcarrying body or platform are separable, whereby the chassis may be incontinuous use, one of such bodies being loaded off the chassis whileanother containing the load is being transported thereon.

The object of the invention is to provide a motor truck of thischaracter in which the load carrying body may be easily shifted onto oroff the chassis and in which Such body will have a solid support on saidchassis and a rolling support off said chassis.

In the accompanying drawings, Figure 1 is a side elevation of anautomobile truck and removable platform, constructed according to myinvention; Fig. 2 is a plan view of the same; Fig. 3 is a partialsection on the line 33'of Fig. 2; Fig. 4. is a fragmentary sideelevation of the end of the truck and platform, showing also a portionof a yard Wagon adapted to receive said platform; Fig. 5 is afragmentary view of the gripping device hereinafter described; Fig. 6 isa fragmentary side elevation of the same, provided with a chain; Fig. 7is a side elevation of the said removable platform of the truck, showingthe same upon a stationary loading platform, a portion of the main bodyof the truck being also shown; Fig. 8 is a fragmentary end elevation ofthe said rolling platform.

In carrying my invention into effect in the embodiment thereof which Ihave selected for illustration and description, I provide an automobiletruck of any suitable construction having a chassis 1, and I secure tothe same, by bolting or in any suitable manner, side rails 2, the samebeing slanted or sloped ofl at their rear ends forming lifting cams 3 tobetter adapt same to receive the sliding rolling platform hereafterdescribed. At the forward end of the truck is provided a Windlass,whereby power may be transmitted to the rolling platform hereafterdescribed, the said Windlass consisting of pinions and gears 4, mountedin suitable bearings secured to said members 2. The axles of said gearsand pinions, designated as 5 Specification of Letters Patent.

Serial No. 793,405.

and 6, arev braced in any suitable manner, the devicetherefor shown inthe drawings consisting of a tie member 7. The axle 6 of the last gearin the train has a pulley 8 fast thereon, said pulley being preferablynotched for engagement with a chain 9, said chain 9 passing over andaround the pulley 8 and around a sheave 10 pivotally mounted at 11 011across beam 12, said cross beam serving also as a brace for the body ofthe truck 1. The pinions and gears 4 are provided with suitable squaredshanks for the application of the crank as commonly used on this styleof Windlass. The chain 9 is continuous, and one of the links thereofcomprises two side plates 13 and cross-connecting pins 14, and to thislink is pivotally secured a hook 15 mounted in a central stud 16.

As already stated, I provide in connection with the main portion of thetruck, a removable sliding rolling platform. This platform comprises afloor section 17, provided with longitudinal rail pieces 18, as shownmore particularly in Fig. 3 of the drawings, said side rail pieces 18forming side rails which fit and slide against the side rails 2 of thechassis and form a close and steadying connection between said platformand the chassis. These rail members 18 are shown as being of thestandard type of structural steel, but this construction is notessential, and the rail members can be made of wood or any othersuitable material. The rails are shown as being curved or flared out attheir ends, the purpose of such flares being to guide or automaticallyaline the rolling platform with the truck when the platform is to berolled or mounted upon said truck. The floor 17 of the rolling platformis preferably mounted at the bottom edge of the ends, and can bereinforced by strips 20 screwed thereto for cooperation with metalstrips 21, secured to the top of the members 2 of the chassis of thetruck. This rounding at the end of the platform, cooperating with thetapered portions 3 of the longitudinal members 2, compensates for anydifference in the levels of the body and the truck, when it is desiredto place the platform upon the truck.

Any suitable means may be employed for detachably connecting thetraveling platform with the endless chain. In the form shown, theplatform is provided with a grappling device adapted to engage with thehook 15 on the endless chain 9. This delPatented Jan. 11, 1916.

vice can be made in many forms, but in the form illustrated in thedrawings it comprises side arms 22 having U-shaped bearing ends, thesame engaging the floor 17, top

and bottom, and having bolts through said" bearing pieces 23 and thebottom 17 of the body. A bolt 24 passes through holes in enlargedportions 25 of the side pieces 22, and the hook 15 on the endless chain9 engages with said bolt 24, whereupon, by the turning of the Windlass,the body will be drawn either off or on, as the case may be, accordingto the direction of rotation of the Windlass. To prevent deflection upor down of the chain 9, which might perhaps cause the chain to jump thesheave 10, I provide a T-shaped arm 26, (see Fig. 5) secured to the body17, between the side pieces 22, the outer end 27 extending down beneathand between said side pieces 22, and being rigidly held by a cap-screw28, passing through a plate 29, and threaded into'said T-piece near theouter end 27.

In the case of a lumber truck, the platform can be provided with theusual form of crib 30, (see Fig. 1) having a loose roller 31 at one end,and a roller 32 capable of manual rotation by a ratchet and pawloperated lever 33, the load in this case being sustained by the rollers31 and 32, and capable of ready removal from the body by the release ofthe pawl on said ratchet and the rotation of the roller 32.

In the embodiment shown in Figs. 7 and 8 the traveling platform isprovided with steadying side rails 35 which engage or straddle siderails 36 of the chassis, corresponding to the side rails 2 and 18 of theother figures. The platform in this embodiment has slide contacts withthe side rails 36 of the chassis, which constitute the load supportingsurface thereof. The traveling platform in these figures is alsoprovided with roller contacts 34 adapted to support the platform whenoff the chassis. The bearing plane of the slide contacts is above thebearing plane of the roller contacts and the lifting cams 3 are of adepth corresponding to the distance between said planes. In this Fig. 7the platform is shown as having uprights 37 and rails 38, and loadedwith boXes 39. The truck in this figure is shown as backed up to astationary loading platform 40, and the hook 15 on the endless chain 9is in engagement with the stud or bolt 24, the platform being inposition to be drawn on to the truck.

When the platform is drawn completely on the truck, it is held in suchposition by hinge-plates 45, having holes 46 thereincooperating withstuds 47 on the truck, said hinge-plates being capable of swinging upand down, and when the body is in position on the truck, said hingeplates thereupon 55 being swung down, the studs 47 passing through theholes 46 in said hinge-plates, said hinge-plates being held fromswinging out of cooperative position by pins48 being placed in positionin holes 46 in said studs 47.

The advantages of my invention will be evident to persons skilled in theart to which the invention relates. Owing to the high cost of automobiletrucks, it is necessary that they be kept in active use in thetransportation of goods for as large a proportion of each day aspossible, since the time occupied in loading and unloading while thetruck stands idle, is wasted so far, as the earning capacity of thetruck is concerned.

By using a truck constructed according to my invention, and providing aplurality of removable platforms to be used in connection therewith, itis possible to keep the truck in active use to the maximum extent. Theplatform can be loaded at leisure while the truck is away, and upon thereturn of the truck the empty platform thereon may be removed and aloaded one placed on instead, and the truck immediately sent out onanother delivery trip. Where goods are loaded from various parts of ayard, a socalled yard-wagon of any suitable construction may be employedand the platform carried thereon from place to place in the yard, or ifthe loading is done from a stationary elevated loading platform as shownin Fig. 7 of the accompanying drawings, the movable platform may berolled to and from the truck when it is backed up to said stationaryplatform.

Another advantage of my invention is that it permitsthe use of variouskinds of carrying bodies, that is to say, movable platforms, upon thesame chassis.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is as follows:

1. A motor truck comprising a chassis, a traveling platform movable ontoand off said chassis, slide contacts between said elements, rollers onsaid platform forming roller contacts therefor in a plane below theplane of said slide contacts, said slide contacts coming into slidingengagement in the onward and ofi'ward movements of the platform andafiording a steadying bearing therefor during the travel of the chassis,said roller contacts supporting said platform when off the chassis andacting in conjunction with said slide contacts to support said platformduring its onward and offward movements, and inclines between saidplanes adapted to guide said platform from one plane to the other in theonward and ofl'ward movements thereof.

2. A motor truck comprising a chassis, a traveling platform movable ontoand off said chassis, slide contacts between said elements, rollers onsaid platform forming tacts coming into sliding engagement in the onwardand oifward movements of the platform and affording a steadying bearingtherefor during the travel of the chassis,
